<p>I had a closer look at this issue and the linked comments: I am not completely sure it affects a tier 1 platform, my understanding is that it affects the windows 32 bit "world" so to say. The problem seems to stem from installing <em>32 bit node js</em> stuff over Windows 64bit , see linked issue <a href="https://github.com/napi-rs/napi-rs/issues/297">#1</a> and  <a href="https://github.com/swc-project/swc/pull/1244">#2</a></p>
<p>This comment mentions that on <a href="https://github.com/rust-lang/rust/issues/67497#issuecomment-568212068">Win 64bit</a> cannot reproduce.</p>
<p>So, unless I am wrong we have a tier 2 platform case here, which (imo) would warrant a <code>P-high</code> (or lower?) and/or a <code>I-nominate</code> flag</p>
